Act 5, Scene 1: At Macbeths castle, a gentlewoman (Lady Macbeths servant) speaks to a doctor about Lady Macbeths strange somnambulatory behavior. While the two are talking, they suddenly observe Lady Macbeth sleepwalking. She vigorously rubs her hands, as if trying to wash away a stain of some sort. Lady Macbeth sighs, weeps and mutters about the Thane of Fife and Banquo. The doctor and the gentlewoman are shocked-Lady Macbeth has inadvertently revealed the source of her distress. Again, lady Macbeth sleepwalks and has nightmares because Macbeth has “murdered sleep.”Act 5, Scene 2: The noblemen Menteith, Caithness, Angus and Lennox rally the soldiers. Menteith reports that Malcolm, Siward, Macduff and the English army are nearby at Birnam Wood and will join them shortly. Caithness informs the group that Macbeth is busy fortifying his castle. The men march on to Birnam Wood.
